Embedded control unit 12 can read battery parameter with predetermined time interval, to save the calculation resources of embedded control unit 12.Described predetermined time interval can be come to adjust in real time according to the current state of battery and/or service condition by system.Such as, when battery dump energy is less, larger charging current can be allowed to charge to battery and the charged state of battery is comparatively safe, therefore in this case, can described predetermined time interval be arranged longer; When the dump energy of battery is larger, larger charging current causes damage to battery easy within a short period of time, therefore in this case, can arrange shorter by described predetermined time interval, to detect battery status better.Certainly, described predetermined time interval also can be arranged by user.Although foregoing illustrates described predetermined time interval, but the disclosure is not limited to this, described predetermined time interval can also be arranged, as long as can realize principle of the present disclosure according to other any suitable method or condition.
If the battery parameter first predetermined condition that embedded control unit 12 reads, then embedded control unit 12 controls to carry out the first process.If the battery parameter second predetermined condition read, then embedded control unit 12 controls to carry out the second process.If the quantity of the battery parameter read is one, then described first predetermined condition is corresponding with this parameter with described second predetermined condition; If the quantity of the battery parameter read is multiple, then described first predetermined condition and described second predetermined condition both can whole corresponding with read multiple battery parameters, also can be only corresponding with the part in read battery parameter.

In the implementation, embedded control unit 12 can comprise battery parameter threshold register (not shown) and battery parameter comparator (not shown), and wherein, described battery parameter threshold register stores at least one battery parameter threshold value; And at least one battery parameter that at least one read battery parameter stores with described battery parameter threshold register respectively compares by described battery parameter comparator arrangement.
Described battery parameter threshold register can be realized by any suitable register well known by persons skilled in the art, and described battery parameter comparator can be realized, as long as can realize principle of the present disclosure by any suitable comparator well known by persons skilled in the art.Herein this is not limited.
In the implementation, can store in described battery parameter threshold register in the battery parameter threshold values such as charging voltage threshold value, charging current threshold value, discharging current threshold, temperature threshold, dump energy threshold value, internal resistance threshold value one or more (hereinafter, if not otherwise specified, then term " battery parameter threshold value " comprises the situation of one or more battery parameter threshold value).
The type of the battery parameter threshold value stored in described battery parameter threshold register is corresponding with the type of the battery parameter that embedded control unit 12 will read.Such as, if the battery parameter that embedded control unit 12 will read is the dump energy of battery and current charging current, then store the dump energy threshold value corresponding respectively with them and charging current threshold value in described battery parameter threshold register, in this case, the dump energy that embedded control unit 12 reads by described battery parameter comparator and described dump energy threshold value compare, and read charging current and described charging current threshold value are compared, so that embedded control unit 12 judges read battery parameter.
In the implementation, electronic equipment 10 can also comprise charhing unit 13.Charhing unit 13 configuration is charged to battery unit 11.
To read a battery parameter with embedded control unit 12 from battery unit 11 below, and this battery parameter is dump energy is example, described first predetermined condition and described first process are described in detail.
In this example, described first predetermined condition is that the dump energy of battery is more than or equal to the first dump energy threshold value.Described first dump energy threshold value can be stored in advance in the battery parameter threshold register of embedded control unit 12.For convenience of explanation, assuming that this first dump energy threshold value is 95%.Correspondingly, described first process is that embedded control unit 12 controls to make charhing unit 13 stop charging to battery unit 11.Assuming that the dump energy of the current reading of embedded control unit 12 is 80%, then embedded control unit 12 wouldn't process; Assuming that after after a while, the dump energy that embedded control unit 12 reads is 96%, then embedded control unit 12 controls to make charhing unit 13 stop charging to battery unit 11, to prevent battery from occurring overcharging phenomenon.It should be noted, the situation supposed in this example and numeral are only for the ease of understanding and illustrate, not forming this example and restriction of the present disclosure.
To read a battery parameter with embedded control unit 12 from battery unit 11 below, and this battery parameter is charging current is example, described first predetermined condition and described first process are described in detail.
In this example, described first predetermined condition is that the charging current of battery is more than or equal to the first charging current threshold value.Described first charging current threshold value can be stored in advance in the battery parameter threshold register of embedded control unit 12.For convenience of explanation, assuming that this first charging current threshold value is that (C is the charge-discharge magnification of battery to 0.2C, 1C represents the charging current be full of by battery for 1 hour required for electricity, and 0.2C represents the charging current be full of by battery for 5 hours required for electricity, by that analogy).Correspondingly, described first process is that embedded control unit 12 controls to make charhing unit 13 stop charging to battery unit 11.Assuming that the charging current of the current reading of embedded control unit 12 is 0.1C, then embedded control unit 12 does not process this; Assuming that after after a while, the charging current that embedded control unit 12 reads is 0.3C, then embedded control unit 12 controls to make charhing unit 13 stop charging to battery unit 11, to prevent from damaging battery because charging current is excessive.It should be noted, the situation supposed in this example and numeral are only for the ease of understanding and illustrate, not forming this example and restriction of the present disclosure.
It is worth mentioning that, in this example, described first process can not be make charhing unit 13 stop charging to battery unit 11, but charging current is reduced to by charhing unit 13 be less than described first charging current threshold value.That is, if the charging current that embedded control unit 12 reads is 0.3C, then embedded control unit 12 can control that the charging current of charhing unit 13 is reduced to and is less than 0.2C, protects battery with this.
In addition, in the implementation, embedded control unit 12 can also read a battery parameter from battery unit, and this battery parameter can be temperature, the charging voltage or internal resistance etc. of battery.Be temperature for battery parameter, in the battery parameter threshold register of embedded control unit 12, be previously stored with temperature threshold.If the battery parameter comparator of embedded control unit 12 judges that read temperature is greater than described temperature threshold, then embedded control unit 12 can make charhing unit 13 stop charging to battery unit 11, or reduce the charging current of charhing unit 13, thus prevent battery temperature too high and bring infringement to battery.
Although foregoing illustrates the situation that embedded control unit 12 only reads a battery parameter, but the disclosure is not limited to this, the quantity of the battery parameter that embedded control unit 12 reads can also be multiple.In this case, described first predetermined condition is corresponding with read multiple battery parameters.
By with concrete example, the first predetermined condition and the first process that read multiple battery parameter and correspondence thereof are described in detail below.
Assuming that embedded control unit 12 reads two battery parameters from battery unit 11: dump energy and charging current.Dump energy threshold value and charging current threshold value is previously stored with in the battery parameter threshold register of embedded control unit 12.For convenience of explanation, assuming that this dump energy threshold value is 95%, this charging current threshold value is 0.2C.In this example, described first predetermined condition is: the dump energy of the battery read is more than or equal to described dump energy threshold value, and charging current is more than or equal to charging current threshold value 0.2C.Correspondingly, described first process is that embedded control unit 12 controls to make charhing unit 13 stop charging to battery unit 11.If at certain particular point in time, the dump energy of the battery read is more than or equal to 95% and current charging current is more than or equal to 0.2C, then stop charging to battery unit 11, thus avoid, when battery dump energy is larger, being caused damage to battery at short notice by larger charging current.The original intention of these two battery parameters of comprehensive descision is, if the dump energy of battery is less, then can suitably allow larger charging current to charge, thus saves the charging interval; If dump energy is comparatively large, then charging current should be relatively little, causes over-charging of battery at short notice to prevent big current.By reading above-mentioned two battery parameters and carrying out comprehensive descision to these two battery parameters, effectively can improve the judgement precision to battery current state, thus more be conducive to protecting battery.In addition, in this example, described first process can not be make charhing unit 13 stop charging to battery unit 11, but charging current is reduced to by charhing unit 13 be less than described first charging current threshold value.
In the implementation, electronic equipment 10 can also comprise Power Management Unit 14.Power Management Unit 14 configuration is powered for electronic equipment 10 by battery unit 11.
It should be noted, the power supply object of battery unit 11 not only can comprise the assembly in the electronic equipment 10 shown in Fig. 1, can also comprise the assembly that such as CPU, display, memory etc. in electronic equipment 10 is such.
Only will read a battery parameter in conjunction with embedded control unit 12 mentioned above below and this battery parameter is the example of dump energy, described first predetermined condition and described first process, described second predetermined condition and described second process are described in detail.
In this example, be described in described first predetermined condition and the example of described first process above, repeat no more herein.Described second predetermined condition is that the dump energy of battery is less than or equal to the second dump energy threshold value.Described second dump energy threshold value can be stored in advance in the battery parameter threshold register of embedded control unit 12.For convenience of explanation, assuming that this second dump energy threshold value is 5%.Correspondingly, described second process can be that embedded control unit 12 controls to make Power Management Unit 14 stop powering for electronic equipment 10.Assuming that the dump energy that embedded control unit 12 reads is 4%, then embedded control unit controls to make Power Management Unit 14 stop powering for electronic equipment 10, to prevent battery from occurring putting phenomenon.It should be noted, the situation supposed in this example and numeral are only for the ease of understanding and illustrate, not forming this example and restriction of the present disclosure.In addition, in this example, described second process can not be that embedded control unit 12 controls to make Power Management Unit 14 stop powering for electronic equipment 10, and can be embedded control unit 12 enter resting state to the CPU transmission sleep request signal of electronic equipment 10 to ask electronic equipment 10.
A battery parameter will be read from battery unit 11 below with embedded control unit 12, and this battery parameter is discharging current is example, described first predetermined condition and described first process, described second predetermined condition and described second process are described in detail.
In this example, described first predetermined condition can be that the discharging current of battery is less than the first discharging current threshold, and the second predetermined condition can be that the discharging current of battery is more than or equal to the first discharging current threshold.Described first discharging current threshold can be stored in advance in the battery parameter threshold register of embedded control unit 12.For convenience of explanation, assuming that this first discharging current threshold is that (C is the charge-discharge magnification of battery to 0.2C, 1C represents 1 hour by the battery under full power state and discharges completely required discharging current, 0.2C represents 5 hours by the battery under full power state and discharges completely required discharging current, by that analogy).Correspondingly, described first process can be that embedded control unit 12 controls to make Power Management Unit 14 remain electronic equipment 10 to power; Described second process can be that embedded control unit 12 controls to make Power Management Unit 14 stop powering for electronic equipment 10.If the discharging current of the current reading of embedded control unit 12 is 0.15C, then embedded control unit controls to make Power Management Unit 14 remain electronic equipment 10 to power; If the discharging current of the current reading of embedded control unit 12 is 0.3C, then embedded control unit 12 controls to make Power Management Unit 14 stop powering for electronic equipment 10, to prevent from damaging battery because discharging current is excessive.It should be noted, the situation supposed in this example and numeral are only for the ease of understanding and illustrate, not forming this example and restriction of the present disclosure.
In addition, in this example, described second process can not be that embedded control unit 12 controls to make Power Management Unit 14 stop powering for electronic equipment 10, and can be discharging current is reduced to by Power Management Unit 14 be less than described first discharging current threshold.That is, if the discharging current that embedded control unit 12 reads is 0.3C, then embedded control unit 12 can control that the discharging current of Power Management Unit 14 is reduced to and is less than 0.2C, protects battery with this.Or, can also to be embedded control unit 12 send sleep request signal to the CPU of electronic equipment 10 enters resting state to ask electronic equipment 10 in described second process, after entering resting state, the discharging current of battery unit 11 will significantly reduce, and realize thus preventing larger discharging current to the infringement of battery.
In addition, discharging current due to battery is excessive or too smallly all can cause damage on battery and then affect battery life, therefore can also further for discharging current arranges lower limit, that is, in example above, described first predetermined condition can be: the second discharging current threshold < discharging current < first discharging current threshold; Described second predetermined condition can be: discharging current >=the first discharging current threshold or discharging current≤the second discharging current threshold.Described second discharging current threshold can be stored in advance in the battery parameter threshold register of embedded control unit 12.For convenience of explanation, assuming that this second discharging current threshold is 0.01C.Correspondingly, described second process can be that embedded control unit 12 controls to make Power Management Unit 14 stop powering for electronic equipment 10, or can be discharging current is adjusted to by Power Management Unit 14 be greater than described second discharging current threshold and be less than described first discharging current threshold, or can be embedded control unit 12 send sleep request signal to the CPU of electronic equipment 10 enters resting state to ask electronic equipment 10.It should be noted, the situation supposed in this example and numeral are only for the ease of understanding and illustrate, not forming this example and restriction of the present disclosure.
Although foregoing illustrates the situation that embedded control unit 12 only reads a battery parameter, but the disclosure is not limited to this, the quantity of the battery parameter that embedded control unit 12 reads can also be multiple.In this case, described first predetermined condition is corresponding with read multiple battery parameters with described second predetermined condition.

Assuming that embedded control unit 12 reads two battery parameters from battery unit 11: dump energy and charging current.The first dump energy threshold value, the 3rd dump energy threshold value, the first charging current threshold value and the second charging current threshold value is previously stored with in the battery parameter threshold register of embedded control unit 12.For convenience of explanation, assuming that the first dump energy threshold value is the 95%, three dump energy threshold value be the 99%, first charging current threshold value is 0.2C, the second charging current threshold value is 0.05C.In this example, described first predetermined condition is: the dump energy of the battery read is more than or equal to described first dump energy threshold value (namely 95%) and charging current is more than or equal to the first charging current threshold value (i.e. 0.2C); Described second predetermined condition is: the dump energy of the battery read is more than or equal to described 3rd dump energy threshold value (namely 99%) and charging current is more than or equal to the second charging current threshold value (i.e. 0.05C).Correspondingly, described first process can be that embedded control unit 12 controls the charging current of charhing unit 13 to be reduced to be less than 0.2C.The object arranging above-mentioned first predetermined condition and the first process uses when being to prevent battery dump energy larger large current charge to cause damage to battery.Described second process can be that embedded control unit 12 controls to make charhing unit 13 stop charging to battery unit 11.Arrange above-mentioned second predetermined condition and second process object be, namely can ensure that battery is full of electricity as far as possible, can prevent again battery nearly under full power state at short notice larger current battery is caused damage.These two battery parameters of comprehensive descision and carry out respectively two kinds process advantages be, if the dump energy of battery is less, then can suitably allow larger charging current to charge, thus save the charging interval; If dump energy is comparatively large, then suitably reduces charging current, to prevent big current from causing over-charging of battery at short notice, and the precision of judgement can be improved, thus be more conducive to protecting battery.
In the implementation, in order to save the calculation resources of embedded control unit 12 and improve operational precision, embedded control unit 12, when whether the battery parameter that reading battery parameter and judgement read meets predetermined condition, can read multiple battery parameter in a predetermined order and judge respectively read multiple battery parameters according to described predefined procedure.
Such as, embedded control unit 12 first can read charging voltage, judges whether the charging voltage read meets the charging voltage threshold condition (such as the first predetermined condition or the second predetermined condition) of battery.If the charging voltage read meets charging voltage threshold condition, then embedded control unit 12 directly controls to process accordingly (such as the first process or the second process); If the charging voltage read does not meet charging voltage threshold condition (such as, neither first predetermined condition, also not second predetermined condition), then embedded control unit 12 reads battery temperature again, judge the battery temperature that reads whether satisfied temperature threshold condition (such as the first predetermined condition or the second predetermined condition), if the battery temperature satisfied temperature threshold condition read, then embedded control unit 12 directly controls to process accordingly (such as the first process or the second process), and by that analogy.
In the implementation, embedded control unit 12 can also configure: if at least one battery parameter read meets the 3rd predetermined condition, then control the operating system at least one read battery parameter being sent to described electronic equipment 10.From hardware aspect, the assembly that embedded control unit 12 can be such with the CPU of electronic equipment 10, display, memory etc. is connected, and provides read battery parameter to them; From software aspect, read battery parameter can be supplied to operating system by embedded control unit 12, so that operating system calls such as EnergyManagement, BatteryCare etc., such battery management software detects better battery status and manages.
